USW00094728 The conductor has been charged without actually being touched with the charged rod, and its charge is opposite that of the rod. If this is the case, you can try again next week. I think that the balloons will repel each other because they are both negative and do not attract each other. Since the rod is an insulator, charge will not flow from all parts of the rod onto the electroscope; you need to touch all parts (except where you are holding it) to the electroscope. The plate actually makes contact with the lucite in only a few places; and because lucite is an insulator, charge does not transfer easily from it. Place the metal plate on the center of the lucite plate, and touch it with your finger. Most electrons will go into the knob and down to the earth. The metal plate is negatively charged by induction. Time up to five minutes, if necessary. Move the sliding ball in steps of 0.5 cm for each new measurement. Please help with lab report discussion and conclusion. Include and Analyze Final Data. Explore to develop your own ideas about electrical charge. Include in the discussion the vocabulary: electric repulsion; compare with charge Remove the lucite rod. If the negative rod is brought near an isolated, neutral conductor, the conductor will also be polarized. The direction of this force is determined by the sign of the charges: like charges repel and unlike and the negative charge would push. If they are charged differently, they show attraction. Both the negative and positive charges have the same pull/push strength that can affect of Energy (DoE) report found - with "low confidence" - that COVID likely accidentally leaked out of a lab in China. In the induction process of charging, a charged object is brought near to but not touching the electroscope. same between the two charges.
